Chart annotations are a powerful feature designed to enhance the understanding and communication of data trends within visualisations. When reviewing a combo chart, it can sometimes be challenging for users to grasp or convey the context behind significant changes in trends represented in the chart. This is where 'Chart Annotations' come into play.

With chart annotations, you can add additional details and insights at specific timestamps on a chart. By attaching annotations to key points of interest, you can provide valuable context and explanations for notable shifts or fluctuations in the data. This feature allows you to go beyond the surface-level interpretation of the chart and delve deeper into the underlying factors that influenced the observed changes.

Chart annotations serve multiple purposes. Firstly, they facilitate a better understanding of the data for the user who created the annotation. By documenting the reasons or events associated with a particular data point, users can easily refer back to the annotation and recall the factors that contributed to a specific trend. This helps you make informed decisions and take appropriate actions based on the insights gained.

Moreover, chart annotations can promote effective collaboration and knowledge sharing within your organisation. When annotations are added to a dashboard, they become visible to other users who have access to that dashboard. This fosters a collaborative environment where team members can engage in discussions, share their interpretations, and exchange ideas based on the annotated insights. It enables users to have meaningful conversations about the data, align their understanding, and collectively drive data-driven decision-making processes.
